J55 K55 N80 Tubing menaka sy fantsona vy Casing
Ny casing solika dia fantsona vy ampiasaina hanohanana ny rindrin'ny fantsakana solika sy entona mba hiantohana ny fiasan'ny fantsakana solika manontolo aorian'ny fizotry ny fandavahana sy ny fahavitan'izany.Ny lavadrano tsirairay dia mampiasa sosona casing maromaro arakaraka ny halalin'ny fandavahana sy ny toe-tany ara-jeolojika.Ny simenitra simenitra dia ampiasaina aorian'ny fampidinana ny casing ao anaty lavaka fantsakana.Tsy toy ny fantsona solika sy fantsona fandavahana, tsy azo ampiasaina indray izy io ary fitaovana azo ampiasaina indray mandeha.Noho izany, ny fanjifana casing dia mihoatra ny 70% amin'ny fantsona fantsakana solika rehetra.
